To all whom it may concern:

Be it known that we, ROBERT W. GILPIN and JOSEPH B. RoMINn, citizens of the United States, residing at Codell, in the county of Books and State of Kansas, have invented certain new and useful Improvements in Detachable Packer-Rims for Harrow-Disks, of which the following is a specification.

This invention relates to improvements in rims for harrow disks.

The primary object of the invention is to provide a rim which may be attached to the periphery of harrow disks, and which may be used as a surface or subsoil packer.

A further object of the invention is to provide a rim disposed to be clamped to the har row disk, the rim being of such configuration as to resiliently engage the disk when in clamped position, preventing movement of the rim with respect to the disk.

Another object of the invention is to provide a sectional rim, the sections of which are so hinged that the periphery of the rim is not enlarged at the hinged point.

A still further object of the invention is to provide a hinged connection, one of the members of which receive the disk, the disk locking the sections together independent of the m ans which connect their free ends.

In the drawings, Figure 1 is a perspective view showing the rim arranged on the disk; Fig. 2 is an assembled perspective; Fig. 3 is a transverse section; Fig. 4 is a transverse section through the hinged connection; Fig. 5 is a disassembled perspective view of the members which form the hinge.

In the drawings, 10 designates one section of the rim which is semi-circular, being formed of tubular resilient metal, the inner face of the rim being provided with a groove 11 which receives the harrow disk. The rim is formed in two sections, being preferably constructed of tubular material, the inner face of the sections being formed with grooves 11. The member 10 is formed adjacent the hinged terminal with extensions 21 and 22, which are provided with cars 23 and 24 disposed in opposite directions, the ear 23 being formed from the outer face of the tube and the car 24 from its inner face, the ears being bent upon the extensions forming bifurcations of double thicknesses of metal, the bifurcations being apertured to receive the pivot pin 16. In forming the female member of the hinge, the inner and outer portions of the rim are severed and slit twice longitudinally along the inner and outer edges, and the metal bent out to form cars 23 and 24, thus providing the bifurcations 21 and 22. Particular attention is called to the construction of this terminal of the member 10, as it provides a rigid connection formed entirely of the material from which the member lOis formed.

The terminal 14 of the section 15 tutes the male member of the hinge of substantially the same formation hinged terminal of the member 10, that it is formed, as shown in Fig. 5, by severing the inner face transversely, and slitting it longitudinally alon one edge. After slitting and severing the metal, as described, the inner edge is bent in to form a constiand Is as the groove 26 having a double thickness of metal on each side, as shown in Fig. 5. The tube walls are then pressed inwardly and flattened sons to be of a suitable thickness to enter between the wings 22 and 23. These double walls are perforated to receive a pin 16. The extension 14, therefore, comprises four thicknesses of material apertured to receive, the pivot pin 16, the four thicknesses being-arranged to form spaced double thicknesses of material, producing the groove 26 which is in alinement with the groove 11 of the sections.

In the formation of both the male and female members of the hinge, it is noted that the extensions are formed from the tubular metal which constitutes the rim. It will thus be obvious that the arrangement is such that the hinge does not project beyond the periphery of the sections, which would normally occur, and which would cause a depression in the soil in excess of that caused by the unbroken portion of the sections.

Each of the sections is provided adjacent its free end with a bracket which is formed with an upturned apertured terminal, a screw 18 passing through the terminal 17 of the bracket 17 which is supportedon the member '10, said screw passing throughthe terminal 19 of the bracket 19 which is mounted on the section 15. A nut 20 receives the terminal 21 of the screw 18, said nut being formed with a flat face 22 which contacts with the section, the nut in this except niannerbeing prevented from rotating. It will be noted that as the screw is rotated, the sections and will be drawn into binding contact with the disk. The sections are sutiiciently resilient to be drawn together, securely clamping the sections on the disk and preventing their rotation with respect to the disk. construction that the rim is effectually held against movement with respect to the disk without the necessity of passing securing devices through the disk.

It will be noted by the peculiar hinged construction heretofore described that should the screw 18 become displaced, the sections will remain on the disk, as it will be impos sible to swing the sections on their hinged connection with the disk inserted within the space 26 ot' the extension 1%, it being noted that the disk bridges the space between the sections and eiiectually locks them against movement. This construction is of a particular advantage as where the rim rotates with respect to the disk, the same readily becomes worn, the sharp periphery of the disk cutting through the rim. In the present construction, it will be noted that the rim will travel at all times with the disk, the sections which form the rim being tightened to compensate for slight variations in the diameter of the disk. It will also be noted that the sections may be readily formed of tubular metal which in being bent to conform to the curvature of the disk may be provided with the groove which'receives the periphery of the disk.

It will be noted that while the sections are shown as formed of tubular metal, they may be solid, yet of such design and sufficiently resilient to produce the desired result.

Having thus described our invention, what Copies of this patent may be obtained for It will be noted by this we claim and desire to secure by Letters Patent is:

l. A rim for harrow disks formed of tubular sections, one of the sections being formed with longitudinally and transversely disposed slits adjacent one of its terminals to produce ears disposed in opposite directions, said ears being bent upon the portions of the section with which they are formed integral, one of the terminals of the other section being provided with a transversely disposed slit and pressed together to form an extension of less width than the section, said extension being disposed between the ears of the other section, and a pivot pin passing through said ears and said extension.

2. A rim for harrow disks formed of tubular sections each of the sections being formed interiorly with a groove, one of the sections being provided with longitudinal and transverse slits adjacent one of its terminals to produce ears which extend in opposite directions, said ears being bent upon the portions of the section with which they are formed integral, one of the terminals of the other section being formed with a transverse slit and pressed together to form an extension of less width than the section, said extension being disposed between the ears of the other section, and a pivot pin passing through said ears and said extension, said extension being provided with a groove which alines with the groove of the sections.

In testimony whereof we affix our signa tures in presence of two witnesses.
